This process describes the steps to execute in order to release a new version of SimPy.
Close all tickets for the next version.
Update the minimum required versions of dependencies in
setup.cfg. Update the development dependencies in
Run tox from the project root. All tests for all supported versions must pass:
$ tox [...] ________ summary ________ py38: commands succeeded pypy3: commands succeeded docs: commands succeeded ruff: commands succeeded mypy: commands succeeded congratulations :)
Build the docs (HTML is enough). Make sure there are no errors and undefined references.
$ tox -e sphinx
Check if all authors are listed in
Update the change log (
CHANGES.rst). Only keep changes for the current major release in
CHANGES.rstand reference the history page from there.
Write a draft for the announcement mail with a list of changes, acknowledgements and installation instructions. Everyone in the team should agree with it.
Build and release
Make local tag for new release. This tag will be pushed later, after checking the build artifacts. If anything is not right, this tag can be deleted and recreated locally before pushing to GitLab.
$ git tag -a -m "Tag a.b.c release" a.b.c
Test the build process. Build a source distribution and a wheel package and test them:
$ python -m build $ ls dist/ simpy-a.b.c-py2.py3-none-any.whl simpy-a.b.c.tar.gz
Try installing them:
$ rm -rf /tmp/simpy-sdist # ensure clean state if ran repeatedly $ virtualenv /tmp/simpy-sdist $ /tmp/simpy-sdist/bin/pip install dist/simpy-a.b.c.tar.gz
$ rm -rf /tmp/simpy-wheel # ensure clean state if ran repeatedly $ virtualenv /tmp/simpy-wheel $ /tmp/simpy-wheel/bin/pip install dist/simpy-a.b.c-py2.py3-none-any.whl
It is also a good idea to inspect the contents of the distribution files:
$ tar tzf dist/simpy-a.b.c.tar.gz
$ unzip -l dist/simpy-a.b.c-py2.py3-none-any.whl
[distutils] index-servers = pypi testpypi [pypi] username = <your pypi username> [testpypi] repository = https://test.pypi.org/legacy/ username = <your testpypi username>
Upload the distributions for the new version to the test server and test the installation again:
$ twine upload -r testpypi dist/simpy*a.b.c* $ pip install -i https://test.pypi.org/simple/ simpy
Check if the package is displayed correctly on the test PyPI: https://test.pypi.org/project/simpy/
Push tag for a.b.c release to GitLab. Upon successful build and test, the GitLab CI pipeline will deploy the tagged release to the production PyPI service.
$ git push origin master a.b.c
Check the status of the GitLab CI pipeline: https://gitlab.com/team-simpy/simpy/pipelines
Check if the package is displayed correctly on PyPI: https://pypi.org/project/simpy/
Finally, test installation from PyPI:
$ pip install -U simpy
